Lens damage?
Jul 5, 2017 09:24:37 #
Good morning, everyone....I'm attaching a picture of my lens to see what you think. Hopefully you can see it ok in the picture...the rim of the lens is bent. I just noticed it not long ago and am wondering if it's something that needs to be repaired. The lens seems to work as it always has..not having a hard time focusing, etc.. (it's a Tamron 70-200 1:2.8). But I'm also including a few photos to see if you see any focus or distortion problems that could be due to this. I don't see any but I don't really have a trained eye for that sort of thing. Thanks for any advice you may have!

It appears as though the actual lens is fine, but will it take a filter?

SteveR said it. I doubt if will still accept a filter - and perhaps even a hood or lens cap. And it may have lost some of its permeability. And I doubt very much if it can be fixed.

Good point about the filter. I don't currently have one for this lens. The lens cap fits fine. And the lens hood met an untimely death in Paris when someone bumped it and it fell off the camera and rolled into traffic, getting crushed to a zillion pieces. 
Incidentally, this damage did not come from the Paris incident...that was some time ago and this damage is recent. Not sure how it happened. Thanks for the input!

This is probably the perfect example of why one should use a clear filter....not just to protect the lens, but the rim. My guess is that most camera drops end up lens down rim first. Better to bend a clear filter than the rim of the lens. Alternatively, have good insurance that will either fix or replace the lens.

The dust integrity of the lens is in question. While all lenses "breathe" as they move, the design is to allow minimum air penetration, you may be pulling more dust into your lens when you rack it back and forth.

This is a very good point and I'm sure you are correct. It's not something I thought of. I'm not sure if it can be fixed or if I just let it go and see what happens. Thanks for your input. By the way, I looked at your website. Very impressive!

You can't take photos of subjects like this to see if there is any distortion from the damage (unless the damage were severe). Set up your camera on a tripod to shoot parallel to a sheet of graph grid paper or like that has straight lines vertically and horizontally. Any distortion will show up with that to some degree.

I have no doubt it can be fixed. You will get your best answer from Tamron. I've had lenses with far worse damage - dropped a 24 PC-E on the rocks. Filter ring was completely bent. and folded over. No damage to the glass. It got fixed. Not cheap, but much cheaper than replacing it, even with a used one.
If this is a current model, and Tamron has or can get the parts, they will fix it.

That was my first thought. I wonder if a dab of clear silicone would be advisable.

I would consider getting it repaired. It seems like I send in a lens about every six months for repair. Of course, I'm hard on equipment.

Your lens is working fine and the bent ring is just a cosmetic issue. If cosmetics bother you as much as they bother me have the lens repaired.

I must agree with SteveR about insurance. I just had my gear insured by State Farm and it covers anything that I damage or gets stolen. It costs me $238 a year to have $16,500.00 coverage which one lens damage this is a small price to pay to be covered. https://www.statefarm.com/insurance/home-and-property/personal-articles-policy

In a WORD - - - NO!
It in all probability is repairable. But cost vs. benefit advisable.
